The Letter Teth (or Tes) has a size of 3X3 kulmusim. The left head of the Teth should look like the head of a Zayin, having completely squared corners and 3 Tagin on top of it. The lower left corner of the Teth should be squared as well. However, the lower right corner should be rounded. The right head of the Teth should curve inside the Teth, not far enough to touch the base of the Teth, but rather enough so that it's clear that it is curved inwards. The two heads of the Teth should not touch each other, as this would make it invalid.
